5 Operation and settings
5.1 Turning the device on
If the device is connected to the power supply, the firmware starts.
If the firmware was closed with
Shut Down
, the device has to first be
disconnected from the power supply and then connected again before the
firmware can start.
Once the firmware has started, the following things occur automatically:
• The measuring process starts. The data is automatically stored in the
internal memory. It takes about two minutes before the first PM values
are displayed.
• The firmware dashboard used last appears.
The warm-up time, from switching on the device until valid measured data is
available, is about 10 to 15 minutes.
5.2 Firmware
The device’s firmware is displayed on a touch screen. On the model AQ
Guard Ambient , the screen is located under the weatherproof housing, so
during operation it is not visible and cannot be directly operated.
There are different ways to access the AQ Guard Ambient firmware:
• Access via Remote Desktop;
refer to section " Access to firmware via Remote Desktop [

• Access to the screen after detaching the weatherproof housing;
refer to section " Operating AQ Guard Ambient without weatherproof
